The Evolution of Android Graphics in Android 12/13
summary
Android 12 and 13 add RenderEffect (view and Compose blur/color filters backed by Skia) and RuntimeShader (AGSL fragment shaders usable as paint brushes or to sample view contents). RenderScript is deprecated; migration options are Vulkan compute on Android 10+ or the open source RenderScript Intrinsics Replacement Toolkit (NDK) which often runs faster than old RenderScript intrinsics. Practical tips: use hardware buffers + ImageReader + recording Canvas to produce bitmaps with no extra copies, prefer Vulkan compute for GPU work, profile for best perf.
